The buds are extended into green fusiform, or onionlike galls. Average size about 6 mm. long and 3 mm. in diameter. Mostly swollen at their base and ending in a point. Inside there is a wide larval-chamber. AU the galls found by me were empty, but it is probable that the gallformer is a caterpillar. See the accompanying figure 7.

On the underside of the leaf thèse galls form small conical outgrowths, situated mostly near the main nerve; they are of a light-green colour. See figure 8. The average size of thèse outgrow^ths is 1 mm. On the reverse side thèse galls are seen as small rounded hardly visible swellings. The opening, which gives entrance to the gallchamber is on the underside of the gall. New-Territory, Sha-Tin, underbrush, 10 Nov. 1920. No. 4948. No. 9. Eugenia Millettiana Hemsl. (prob). A stem-gall caused by a gallmidge. The endsof the twigs are swol- len into irregular ballshaped or oval galls. They consist of the stem-apex, and sometimes rudiments of the leaves are developed on the gall. Occasionally they can develop in the axils of the leaves. Average size 3—6 mm. in diameter. Inside there is a watery tissue in the centre of which are several small rounded larval-chambers. Se
